This jack modification is expected to be an efficient and economical way to remove bearings.

In general Bottle Jack serves as a mechanical tool to release bearings manually.

A jack is one of the tools that we usually encounter when our car needs a tire change. Or we usually meet a lot in car repair shops. But maybe the type of jack is not only that. There are many types of jacks that you must know, especially as a contractor.

The jack itself is a device whose operational technique uses force to lift heavy loads. The main mechanism used to apply force varies, depending on the specific type of jack, but is usually a screw thread or hydraulic cylinder.

Jack categorization is based on the type of force used, namely mechanical or hydraulic force. Mechanical jacks, such as car jacks and house jacks, are usually used to lift heavy equipment. This category also looks at lifting capacity (for example, the number of tons they can lift).

In some types of jack categories, hydraulic jacks are considered more powerful in lifting heavier and higher loads. One type of hydraulic jack is the floor jack and bottle jack.

Hydraulic jacks rely on the force generated by pressure. Basically, if two cylinders (a large one and a small one) are connected and force is applied to one cylinder, the same pressure is generated in both cylinders.

Hydraulic jacks are jacks whose operational techniques use liquid to push the piston contained in the jack. The use of this hydraulic jack refers to Pascal's Principle.

Pascal's Principle states that the pressure in a closed container is the same at all points. If there are two cylinders connected, exerting a force on the smaller cylinder will produce the same amount of pressure on the larger cylinder. However, since the larger cylinder has more area, the resulting force will be greater.

In daily life, the use and modification of bottle jacks are used to remove electric motor bearings. Bottle jacks are usually also used on water pump machines.
